PATENT .OFFICE PENNSYLVANIA, ASSIGN OR TO HUNT BROTHERS & COMPANY, (LIMITEDQ OF SAME PLACE.

* MIvNERS LAMP.

SPECIFICATION forming part of Letters Patent No. 279,503, dated June l2, 1883.

Application filed March 20, 1382. (Xo modul.)

To all whom t may concern:

Beit known that I, EDWARD K. RoLLINs, of Scranton, in the county of Lackawanna, and State of Pennsylvania, have invented certain Improvements in Miners Lamps, of which the following specication is a description.

rlhis invention relates to improvements in miners lamps, the invention consisting in making the spout and cylindrical. portion or body of the lamp out of one piece oi' metal stamped or otherwise formed up to the desired size and shape, and having a separate bottom and breast attached thereto, as by soldering, all as hereinafter specically set forth and claimed.

' In the accompanying drawings, Figure l is a side view of a miners lamp embodying my improvements. Fig. 2 is a central longitudinal section thereof; and Fig. 8 is a perspective 2o VieWjof my combined cylinder and spout.

Similar letters of reference indicate corresponding parts in all the figures.

A designates the cylindrical portion or body of the lamp, having its spout B made of the 2 5 same piece of metal. This cylindrical portion A is provided at its upper end with a breast,

C, having a wide mouth or opening, into which a stopper or cap, D, is arranged to fit snugly to close the opening. The lower end of' the 3o cylindrical portion A ts into a bottom, E,

which may be soldered or otherwise secured thereto. The cylindrical portion A and its spout B are stamped up out of one piece of Vmetal, and the edges a. c and b' b are overlapped and soldered or sweated or otherwise securely connected to make a iiuid-tight joint.

A miners lamp made in accordance with my invention possesses the following advantages over the old form: First, the spout and bodybeing without connectingjoints, there is 4o entire absence of the dripping of the oil that Ahas heretofore been a source of annoyance and discomfort to miners; second, miners lamps are exposed to hard usage, and are bent and battered to such an extent as to start the seams in the ol d forms, producing leakage and rendering the lamp practically useless. I avoid the leakage and the other evils resulting from damage to the lamp by discarding seams, and making the lamp-body and its most 5o exposed part (the spout) in one piece.

I am aware that coal-hods and some other vessels have been made with the mouth and body in one piece, but I am not aware of the prior existence of a miners lamp made as 5 5I herein shown and described. y

What I claim as my invention, and desire to secure by Letters Patent, is

l. A miners lamp having its spout B and the bodyA formed together as one piece with- 6o out uniting seams, substantially as shown and described.

2. The combination, substantially as shown and described, of the body A, seamed at c a, and the spout B, seamed at b b, the two being made of one piece without connecting-seams, with the bottom E, breast C, and cap D, as and for the purpose specified.
